Emergency preparedness and recovery are critical components to safeguarding our communities.

Year after year, we are reminded of how dependent we have become on the underlying infrastructure that delivers the clean water, electricity, and communications we often take for granted. It is only after a hurricane, tornado, flood, ice storm or earthquake has knocked out our utility systems that we realize the ramifications of losing access to these fundamental services.

The graphs to the right illustrate an unmistakable rise in the number of natural disasters, as well as their increased intensity.

There is often a large cost impact for businesses without backup power in the event of an extended utility power outage; municipal facilities without power can cause severe social problems. Being diligent and taking appropriate steps to minimize operational downtime is good business practice. While some standby power solutions can be quite costly, ESL’s pre-wired emergency power connection equipment is very cost-effective when comparing all the separate pieces of alternate solutions. In addition, our emergency power products provide users with safe and simple operation so that grid-tied facilities can quickly connect to portable power.

StormSwitch™

Manual Transfer Switch70A – 800A Wall MountESL’s UL/cUL 1008 Listed StormSwitch manual transfer switch is the ideal solution for portable generator connection to grid-tied facilities. StormSwitch combines a robust commercial-grade transfer switch with color-coded cam-style connectors for quick connection to a portable power generator. Integral utility and generator manual disconnects are interlocked to prevent cross connecting the power sources. Once installed by a licensed electrician, the StormSwitch is so easy and safe to operate that only basic training is required. Buying and installing automatic transfer switches with a permanent generator for each site can be quite costly and requires ongoing maintenance. With StormSwitch, multiple locations can be equipped with a manual transfer switch and share a single portable generator, a significant cost savings.

3-way Manual Transfer Switch125A - 800ALoad bank testing can be challenging and time consuming. In addition, the process leaves critical operations systems (COPS) susceptible to power loss during testing since the permanent generator has been disconnected from the system. ESL’s TripleSwitch is a dual purpose solution to service critical operations facilities that utilize an automatic transfer switch and permanent generator. The TripleSwitch provides three interlocked disconnects to isolate standby generator circuits during load bank testing, while providing the additional benefits of ESL’s StormSwitch manual transfer switch. This ensures that a quick, safe method to connect to a portable generator for redundant backup power is available. ESL’s TripleSwitch combines generator quick connects for redundant backup portable power at a much lower cost, smaller footprint, and can virtually eliminate wiring mistakes.

Why UL 1008 Should Be Specified

What are the advantages/disadvantages of using a manual transfer switch with a portable generator versus an automatic transfer switch with a permanent generator?Advantages:• Significantly lower cost • No on-site fuel storage required• No maintenance or standard

periodic testing• Easier installation – days instead

of weeks• Smaller size • Portable generator can be rented

or used at other facilities• Does not require multiple permits

that a permanent generator would

Disadvantages:• Longer time before generator

power is established

What is UL 1008 and how does it affect me? Local building inspectors typically require all new electrical equipment installed in their jurisdiction to be “Listed” which means the equipment has been approved by Underwriter Laboratories or another recognized test lab. For standby systems that allow portable generator connection, UL 1008 is the proper standard for manual transfer use. If the equipment is not Listed, it may not be acceptable to the inspector.

Can’t I just connect my generator directly to my panel?Accidentally backfeeding the utility grid can be very dangerous. For a direct connection you would need a Certified Electrician available anytime you needed to hook up your generator. There are other methods

and products available for powering up from a portable generator, but the StormSwitch is the best product available that combines the simplicity of cam-style connectors with a safety interlock device that prevents back feeding the utility grid.

Can vandals open or steal the StormSwitch? Can they shut off my power?Once installed, the device is always in use. The StormSwitch door can be padlocked, preventing unauthorized entry. The disconnect handles can be padlocked in the “OFF” position for further security. With a minor modification, the disconnect handles can also be padlocked in the “ON” position, however, this is not recommended. For complete security the StormSwitch is equipped with a lockable handle cover to prevent unauthorized use.

Where can I make conduit penetrations on the StormSwitch?Conduit line/load penetrations can be made around the top portion of the enclosure (top left, top right, top back, top top) and/or bottom left of the enclosure only. For the StormSwitch BeBe, conduit line/load penetrations can only be made through the bottom left side of the enclosure.

Can the StormSwitch be Service Entrance Rated?Yes, the StormSwitch has the option to be SUSE (Suitable for use as Service Entrance in the USA). This option should only be used when the StormSwitch is installed at the building service entrance.

I am in Texas. Can the StormSwitch survive the rain/heat/cold/bugs here?The StormSwitch is a Type 3R enclosure. This means it is suitable for outdoors and will protect components from rain. To ensure that insects, debris, small animals do not enter the enclosure, ESL provides a hinged cover over the cam openings in the bottom of the enclosure that is locked closed when the door is shut.

What is the TripleSwitch designed to do?The TripleSwitch was designed to simplify and reduce the cost of load bank testing procedures in addition to providing a backup for the backup. This unique 3-way manual transfer switch system provides a quick and completely safe way to supply power to the facility from a portable emergency standby generator during load bank testing in the event the utility power is disrupted due to a power loss or if the permanent generators are offline.

Is it difficult to make the generator connection to the StormSwitch, TripleSwitch or TempTap product line?No, they utilize the industry standard 400A series 16 cam-style connectors. ESL’s StormSwitch, TripleSwitch and TempTap are color-coded to the voltage, e.g. 208Y/120 green, white, black, red, blue.

How do I know what product will best work with my specific needs?ESL’s knowledgeable sales personnel will gladly assist with helping to identify the proper product for your application. The key factors will be the voltage system and the desired emergency load that is to be fed.

When comparing NRTL Listings of different products, it is important to know what the appropriate UL standards are and how they apply to your specific application. You may not always be purchasing what you think you are. UL 1008 is specifically designed for transfer switch equipment. Products with a UL 1008 certification means the whole assembly is certified and has undergone rigorous testing to ensure performance, safety, and reliability. Non-Automatic transfer switches that are Listed under the UL 1008 standard are evaluated in accordance with Articles 517-Health Care Facilities, 702-Optional Standby Systems of the National Electrical Code (ANSI/NFPA 70) and the National Fire Protection Association Standard for Health Care Facilities (ANSI/NFPA 99). The inspection process is also easier when emergency power transfer switch equipment is UL 1008 Listed.
